About PSCI

The Power Sector Carbon Index provides an estimate of the carbon dioxide (CO2) intensity of the U.S. power sector using publicly available data sources. Carbon intensity is measured in pounds of CO2 per Megawatt-hour (MWh) of electricity. All of the charts and data are directly downloadable from the site. Read more about how the Power Sector Carbon Index is calculated here. The Index was created by researchers in Carnegie Mellon University’s Scott Institute for Energy Innovation, with support from Mitsubishi Hitachi Power Systems.
